Answer:
water that flows over the ground and can carry pollution to water. Algal blooms choke out other plants and decrease the amount of oxygen available for living organisms.
Explanation:
Unmyelinated axons and neuronal cell bodies make up the majority of the grey matter.
The processes that emerge from the cell bodies of neurons and transmit messages between those cell bodies are known as axons.
These axons are primarily unmyelinated in the grey matter, which means that myelin, a whitish-colored, fatty protein, is not covering them.
In the brain, the grey matter is used to process information. Grey matter structures analyze signals produced by sensory organs or other regions of the grey matter.
This tissue sends sensory (motor) stimuli to the central nervous system's nerve cells, where synapses cause the nerve cells to respond to the stimuli. Through myelinated axons, which make up the majority of the white matter in the cerebrum, cerebellum, and spine, these impulses travel to the grey matter.

When glucose is high, cAMP is low; CAP does not bind the lac operator, and RNA polymerase does not bind the lac promoter. CAP is only active when glucose levels are low, which means the cAMP levels are high, and therefore the lac operon can only be transcribed at high rate when glucose is absent. The importance of this is that the bacteria only turns on the lac operon and start using lactose only after they have used up all the preferred energy source which is glucose.
Answer:
Meristematic tissue
Explanation:
Meristematic tissue contains actively dividing cells that result in formation of other tissue types (e.g. vascular, dermal or ground tissue). Apical meristematic tissue is found in buds and growing tips of plants.
Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. Cells also divide so living things can grow. When organisms grow, it isn't because cells are getting larger.
